Animal of moderate size, its general outline, including tlie arms, more or less spindle-shaped. Body short, robust, bluntly conical, widest near the front, and tapering to a rounded point behind; texture firmly semigelatinous; mantle thick, its anterior mar- gin rotmded, somewhat emarginate below the funnel with very obtuse lateral angles, barely produced above to form an obscure anteriorly projecting angle in the median line. Lock- ing apparatus well developed; nuchal cartilage a somewhat spoon-shaped plate; on either side of the base of the funnel a heavy, deeply excavated, pyriform cartilage, terminated by a broadly , membranous margin (pi. u, fig. 5). Fins short, broad, semi- circular, together forming a transverse ellipse; about two- fifths as long as the mantle; well lobed in front and behind; posteriorly not at- tached as far as Uie extreme tip of the body, but broadly continuous with one another above it. Head , strongly asymmetrical, de- flected to the right so that its longitudinal axis shows a di- vergence of some 30° from that of the body; tliis state apparently brought alx)ut chiefly through the extraordinary development of tlie left eye, which includes nearly one-half of the total bulk of the head, the diameter of its lid opening more than twice that of the right (pi.
